Design Review #1 - Low Fidelity Prototype (21/10/2013)

We conducted a Heuristic Evaluation to test out the design of our application. This is to learn more about the useability of our application and improve it further in our future designs. We used our interactive prototype in InVision for this design review. Our participants are SMU students from different faculties so as to broaden the feedback gathered.
